| Abstract | The behavior of hysteresis as a controlled plant obviously changes with not only the history of input, but also the compressive stress and excitation rate experienced. In this paper, a generalized dynamic Preisach operator is proposed for describing the dynamic hysteresis nonlinearity under varying compressive stress, excitation rate, as well as their couple effect, which can also be expanded for other varying factors, such as temperature, etc.. The developed operator features introducing the dependence of the density function on the compressive stress and excitation rate to the classical Preisach operator by a multi-criteria decision-making evaluation framework. The parameter identification scheme employing a fuzzy tree method is investigated to formulate the inverse compensator. On accounting of application, a feedback control scheme combined with a feedforward compensator is implemented to a magnetostrictive smart structure for real-time precise trajectory tracking. Both simulations and experiments demonstrate the proposed operator and corresponding control scheme a dramatically improved performance of mitigating the effects of hysteresis. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
